The AHDB Crop Walkers’ Guide app is designed to help growers, supervisors and technical staff make quick diagnoses while out and about.

The guides include the names of pests and diseases, photographs to help identify what you have found and control and prevention methods. You can also file a report when you find a pest or disease so that you can keep a log of locations, dates etc.

The app, which is based on AHDB Horticulture’s popular Crop Walkers’ Guides, also allows users to log the GPS location where symptoms were spotted while on nursery, in store and out in the field.

The guides included in this app reflect AHDB Horticulture’s printed Crop Walkers’ Guides. Representing the interests of growers from across the protected ornamental and edible sectors, as well as field vegetables, soft fruit and tree fruit, this Crop Walker Guide App is designed to help you identify pests and diseases whilst crop monitoring.

The following Crop Walkers’ Guides are included within the app:

Protected Edibles
Field Vegetables
Bulbs, outdoor flowers and protected ornamentals
Soft Fruit
Hardy nursery stock
Tree Fruit

More guides will be available soon.

Please note: Your device will need over 1.0 GB of free space available if you intend to download all of the guides. Please refer to your device settings to check the available storage. We suggest that you only download the Crop Walkers’ Guides relevant to you and your sector – selecting to download all of the guides will use up a large amount of storage space on your phone, due to the high quality of the images.

The first time you launch this app you will need a Wi-Fi or mobile data connection, after that all guides will be available offline.

In many cases AHDB Horticulture has produced a vast range of supplementary reading and if you need to find out more about the pest or diseases you have identified then click through to our publications portal for detailed information.
